Notes:
1. In the Type/Dir column, Output is from Jetson AGX Xavier. Input is to Jetson AGX Xavier. Bidir is for Bidirectional signals.
2. The direction indicated for the UART pins is true when used for that function. Otherwise, these pins support GPIO functionality and can support
both input and output (bidirectional).
